From the Scientific American: "Why Aren't More Women Tenured Science Professors?":
Women who apply for tenure-track positions at top-tier research universities in math and sciences these days have a slightly better chance of landing the job than their male colleagues, says a new study funded by the National Science Foundation.
But that's just for those who apply, which is a good tick lower than those who earn PhDs. In chemistry, for example, women made up 32 percent of newly minted PhDs from 1999 to 2003 but accounted for only 18 percent of applicants to tenure-track positions.
From UVA Today: "Citizens in 34 Countries Show Implicit Bias Linking Males More Than Females with Science":
Implicit stereotypes – thoughts that people may be unwilling to express or may not even know that they have – may have a powerful effect on gender equity in science and mathematics engagement and performance, according to a new study published this week in the Proceedings of the National Academy of Sciences.(h/t: Alice of Alice's Astro Info)
The international study involving more than half a million participants in 34 countries revealed that 70 percent harbor implicit stereotypes associating science with males more than with females. Moreover, in countries whose citizens stereotyped most strongly, boys achieved at a higher level in eighth-grade science and math.
